Caver exploring Cwmorthin Slate mine

Caver Peter Hamilton dangling over a deep shaft in Cwmorthin Slate mine, near Blaenau Ffestiniog. Pete was sliding along a metal wire using a pulley, attached to the harness he was wearing. Several of these wire traverses have been installed into this part of the mine and link together so Pete continued along the passage and disappeared into the darkness. When he returned - it was my go :-)
